Protools Question

I've got a small home studio where I dabble in all kinds of fun (small kittens, pretty women...oh yeah, and sound!)

Anyway, I've been looking into getting a pro tools rig set up. My question is this: is there any reason why I can connect my existing mixing board (which has all my hardware--and that kitten--plugged into it) into an MBox?

I know the MBox is only 48khz and not 96, but technically this should work, right?

What problems might I expect from this setup?

In case anyone cares, I just feel like I've outgrown my old setup---it sounds about as good as its going to...and am interested in learning Pro Tools.
